HELP, IM CHANGING MY MAJOR AND I DON'T KNOW WHO TO TAKE!!!!!

Well for Calculus I, I was told to take Chen. I know people who took him and they said he was decent. For Intro to Black Diaspora I, I took Shango but I don't believe he is teaching it Fall semester. For Gen Chem I, I took Prof. Zuk my freshman year. They don't have his name up there but I believe he is teaching the class that is MWF 1310-1400. You can call the chem dept. to make sure. He is a really good teacher im my opinion, plus he doesn't make chemistry as hard as it could be. For Gen Chem Lab I, I don't recognize the professors teaching it Fall semester. For Physics for science & engineering I, there is only one teacher (Alfred) and the lab is taught by a TA so you wont know who it is until you get there.
